I had no problem with FXS to x-lite, do you have the latest SVN trunk or one
of the tarballs? We may have fixed some issues if you have an older release.
We have an application you can use in the dialplan called set_user
for example put this as the very first extension in the dialplan
<extension name="set_openzap_user" continue="true">
<condition field="source" expression="mod_openzap"/>
<action application="set_user" data="${caller_id_number}@$${domain}"/>
</condition>
</extension>
if you put that in an extension at the top of your dialplan just for calls
from openzap then you
will make that call assume the settings of the user in the directory with an
id that matches the caller id num set in openzap then fall through to the
rest of the dialplan.
most things you *think* are not possible are just not forced into place =D
as for astribank, I have heard there are a few issues with them and I do not
have one to test them. The guy who supports them is around on IRC but he
tends to favor the AST that's why he calls them ASTribank so we can try to
work with him if he's willing.
